lCar Brakes, of which the following is a specification.

One object ofthe invention is to pro-vide novel brake-shoe heads for use on the ends of the compression and tension members of trussed brake-beams for railway cars, said heads being adapted to receive `the brakeshoes and their securing keys, as usual.

A more specific purpose of the invention is to provideV a novel brake-shoe head of forged metal and of a construction enabling the head to withstandvery great pressure, the head of my invention being capable of withstanding, when resting on its toes, a pressure applied to its back in excess of nine thousand pounds with deflection not eX- ceeding one thirty-second of an inch and with no permanent set.

A further purpose of the invention is to provide a forged brake-shoe head of very great efficiency and at the same time one capable of convenient manufacture with the use of dies and whose parts may be quickly and accurately assembled.

The brake-shoe head ofmy invention comlprises, in its preferred form, two vertical matching` members and a. face-plate,V said vertical members `constituting the body of the head and receiving said face-plate and having parts adapted to receive the adjacent ends of the compression and tension membersv of the brake-beam. Between the front edge port-ions of said verticalmembers and the back of said face-plate is formed a keyway for the usual keyvrequired for detachably securing a brake-shoe against said faceplate.

Une distinguishing featurev of my brake. shoe head is that it is of forged metal and devoid of transverse joints, the upper and lower portions of the head being integral with each other both at the front and at the back of the compression and tension members of the brake-beam and the outerand inner faces of the head presenting` adequate plate sec-tions .to take7 on edge, the thrusts that may he exerted against the head.

In the present construction of the. head, the outer and inner vertical members thereof have an nterengaging connection along same,

theirback edges, from the npper end tothe lower end of the head`r andv said membersfare vheldv together at their front edges by being embraced between flanges on the face-plate,

and finally the three parts of the head are firmly secured together by a few rivets, four rivets being sufficient, V.extending through said face-plate and forward flanges formed on said vertical members. 4 i

The face-plate of the head is of suchconstruction and arrangement thatif worn, as .i by engagement with a car-wheel after a shoe hasbeen worn through or lost from the head, it may be removed from the body portion of the head and replaced by anew face-plate. yAny' part of my new brake-shoe head is renewable. i'

The invention will he fully understood from the detailedV description hereinafter presented, reference being Vhad to the accompanying drawings, in which:

Fig. 14 is a vertical section through a portion of the. same, at the upper hanger-opening, taken on the dotted line 14-14 of Fig. 13.

|The brake-shoe head of my invention is of forged plate metal and composed of three members properly secured together to form a complete br-ake-shoe head, said members being an outer vertical member 20 shown separately in Figs. 5, 6 and 7, an inner vertical member 21 shown separately in Figs. 8, 9 and 10 and a face-plate 22 shown in Fig. 4 and' also in Figs. 1, 2 and 3.

The vertical members 20, 21 constitute the main body of the head and are substantially two equal parts each formed from a sheet of metal pressed into shape by means of dies. The face-plate 22 is in one integral piece of forged plate metal out and pressed into shape by means of dies and riveted to forward portions of the outer and inner members 20, 21.

The members 20, 21 are fashioned to be matched together and to receive the end of the brake-beam and also the end of the truss-rod, and to this end the outer member V2O has projected laterally from its flat ver- 'tical` face portion 23 a hollow rectangular section 24 adapted to receive. the end of a channel beam (not shown), and on said boxlike section 24 is an angular outwardly projecting section 25 which contains a central opening 26 through which the end of the truss-rod may be inserted and around which is formed an integral seat 27 for the usual nut or other securing device by which the truss-rod is connected with the brake-shoe head. The box-like section 24 is at the backportion of the member 20, as shown inrFig. 5, and in line with a front recess or opening 28 which is arranged for a brakebeam hanger and located at the back of a wider opening 29 provided for the usual center lug on a standard brake-shoe. The boxlike section 24 is continued forwardly by a section 30 of reduced width which extends to an outwardly projecting lateral flange section 31 which defines the rear portion of the opening 28 and is Vin one part with a flange 32 extending from one end to the other of the forward edge of the member 20, said flange 32 being provided for strengthening the head and also for receiving one longitudinal side portion of the face plate 22 as well as for other purposes. Back of the flange 32 of the member 20 said member is bent outwardly from its main plate portion 23, as at 33, and then forwardly on an outwardly inclined line, as .at 34, whence the metal is bent laterally to form the said n flange 32, this formation affording great strength to the member 20, positioning the flange 32 to properly receive the face plate 22 and forming a section of the key-way to receive the usual key for the brake-shoe.

At its back edge the member 20 is flange-d i or 'U-ed over, from the upper'to the lower end of the member, as at 35, to form a receiving recess 36 for the back edges of the inner member 21, as hereinafter explained. The outer member 2O constitutes substantially one vertical half of the body portion of the brake-shoe head and said member is in one integral piece of plate metal cut and pressed to the outline shown, the member 20 in general outline being that of a conventional brake-shoe head and consisting of the flat plate portion 23 having along its back edge the flange 35, along its front portions the Vlaterally bent and exn tended sections 33, 34, 32 and at its central or neck of said section 24 and merging into the portion 3l of the forward continuous flange At the adjoining portions of the box-like section 24 and extension or neck 30 thereof are upper and lower shoulders 38 which are continuations of the upper and lower sides of said box-like section and its extension 30 and between which is formed a space for the passage of the outer end portion of the truss-rod.

rlhe flange 32 contains a rivet hole 39 in its upper transverse half and a rivet hole 40 in its lower transverse half.

The inner vertical member 21 of the body of the brake-head has a plain flat face porf tion 41 corresponding with the outline of the bodymember 20, and this face portion 4l has flanged outwardly therefrom and toward the middle or inner 'portion of the brake-beam, a continuous forward edge flange 42 corresponding with the flange 32 of the member 20 and having an inset section 43 matching the portion 31 of the flange 32 and providing for the hanger opening 28 and opening 29 for the brake-shoe lug. The plate 41 of the member 21 is also bent laterally, as at 44, and forwardly on an inclined line 45 to meet the laterally bent fianger42, as shown -in Fig. 9, these parts corresponding with the sections 33, 34, 32 of Fig. 6, but extending in an opposite direction therefrom, said sections 33, 34, 32 extending outwardly laterally from the outer face of the outer member 20, Vwhile the sections 44, 45, 42 of Fig. 9 extend outwardly from the exterior face of the inner member 21 and opposite,v to the direction of the bending of the sections 33, 34, 32, whereby the inner portions of the plates 23, 41 of the members 20, 21 are correspondingly deflected in a direction from each other to afford an adequate bearing for the face-plate 22 and provide by the angularity of said bent portions great resisting power in the body portion of the head.

At the back portion of the plate 41 of the member 21, an interior portion of the metal is bent outwardly to form a transverse boX- member 46, as shown in Figs. 9 and 10, and this box-member 46 matches at its interior the chamber 37 formed in the box-like section 24 of the member 20, and constitutes a portion of the receiving socket for the outer end of the compression member of t-he brake-beam. A part of the metal at the forward edge. of the opening 47 created by the formation of the box-like section 46 and which metal was displaced in forming said opening, is folded inwardly and forwardly, as at 48, uponl that portion 43 of the flange 42, which is at the back of the hanger openingv 28, as shown in Figs. 1, 3, 8 and 9, the metal portion 48 not only being bent inwardly along the forward edge of the opening 47 in the member 2l, but between its upper and lower edge portions being bent forwardly to'engage said portion 43 of the flange 42 and therewith form a double-wall around the back edge of the hanger opening 28, as shown by dotted lines in Fig. 8 and solid lines in Fig. 3. The infolded section 48 at the opening 47 is also, at the forward edge of said opening 47, concaved, as at 49, to form a seat forthe truss-rod, the truss-rod having a bearing at the forward edge of the opening 26 therefor in the member 2O and against the seat 49 formed by the folded metal section 48 and also at the edge 50 of the folded section 48, as I indicate by a. dotted line 19 in Fig. 2, said dotted line defining the forward edge line of a truss-rod.

The inner member 21 of the body of the brake-head is plain and fiat along' its entire back edge extending from the upper end of said member 2l tothe lower end thereof and this plain edge portion of the member 21 prevents any lateral separation of said members; lt will be noticed how readily the members 20, 21 may be assembled when it is considered that each membergis formed complete in itself and that the assembly consists merely in sliding the back edge yportions of the member 21 into the', recess 36 of the rmember 20. After the parts 20.v 21'hare been brought together the flange 35 may be tightened against the member 20 to firmly bind the members 20, 21 in rigid relation to each other.

The face plate 22 is an elongated plate having openings 51, 52 in its upper and lower end portions for the usual brake-V shoe parts and, except atl said openings.y flanges 53 extending along` the ends and sides of said plate, as indicatedby dotted lines in Fig. 4 and full lines in Figs. 1, 2 and 3. The flanges 53 are bent in a direction toward the body portion of the head and closely receive and embrace the' flanges 32, 42 of the members 20, 21 of said body portion, as shown in Figs. 1, 2 and 3. The flanges 53 are at bot-h the ends and sides of the face plate 22, and hence the face plate become accurately centered upon the flanges 32, 42 of the matched and interlocked members 20, 21 of the body portion of the head. After the members 20, 2l have been brought together, with the edge of the member 21 within the recess 36 of t-he member 20, and the face plate 22 has been applied against the flanges 32, 42 of said members, the assembly of the head is complete withthe exception of riveting the face-plate 22 in place, and to this end form. the face-plate vwith rivet holes 54, to match the rivet holes 39, 40 in the flange 32 and with rivet openings 56, 57 to match corresponding rivet holes 58,59 in the vflan ge 42, and secure the several parts together by rivets 18 entered in said matched holes.

The face-plate 22 at its transverse middle portion bends inwardly closely along the recesses 29, 28 provided in the body members 20, 2l for the brake-hanger and for the middle lug on the brake-shoe, as shown in F ig. 1, and at the upper and lower sides of the opening 29 the metal of the face-plate 22 is slit on three sides and bent over to form openings 60, 61 for the brake-shoe key, not shown, the metal removed at the upper side of the lug recess 29 being folded upwardly against the inner face of the facew plate 22, as at 62, and the metal removed from the lower opening 61 being folded downwardly against the inner face of said 'strenffth tothe olate at the Joints face-pate, as at 63, whereby adjacent to said openings the tace plate becomes o1? double thickness and said folded metal sections 62, 63, aiord bearings for the middle portion of the brake-shoe lrey. rlhe olds or the ietal at the upper and lug recess 29 also impart considerable at which the shoe lug will Contact therewith.

The lateral bends in opposite directions of the members 20, 21 to forni the sections 33, 44 and the forward sections 34, 45 of said members aifiord, when the members 20, 21, are assembled, an adequate key-way 64, as

shown in Fig. 2, to receive the usual brakec t,

tailed description oi the head shown in F shoe key, this key-way 64 being in line with the openings 60, 61 in the face plate 22 and the baclr oit the vertical central portion or said face plate. rlhe 4face-plate 22 .extends continuously along the 'forward face portions or flanges 32, 42 of the members 20, 21 and lines the recesses 29, 23 orined in said members 20, 21, as shown in Fig. 1. The side portions ot the i'langes on the tace plate 22 serve to resist lateral thrust against said tace plate and aid in tying the members 20, 21 of the head together, and the end portions of the iflanges 53, .vhicli engage the upper and lower edges or the body members 20, 21, are important in resisting strains exerted upwardly or downwardly against said face plate, the flange at the upper end c or the plate 22 resisting any force tending to pull the face plate downwardly from the head and the flange at the lower edge of the tace plate 22 resisting any force exerted in an upwardly direction on said face plate. The inwardly looped portion 17 on the faceplate lining the recesses or openings 29, 28 and thereat directly engaging the seat ilanges 32, 42, also materially aids in en` abling the face-plate .to resist vertical strains.

The entire brake-head is thus formed oi three vertical parts matched and flanged together and secured in their assembled relation by the 'flanges and the presence ot four rivets securing the tace-plate or the head to the body members thereof, and the head thus produced is devoid oi' transverse joints and or great eiiciency in that it is capable of withstanding` all the strains to which brake shoe heads are subjected in modern railway practice and equipment.

The brake-shoe head shown in Fig. 11 is identical with the brake-shoe head illustrated in Figs. 1 to 10 inclusive with the exception that i provide in the head shown F" 1 llt lh 0 65 in rig. 1i an accitiona nger recess for use in equipments in which the wheelbase dimensions render the upper recess 65 necessary or desirable. 1n forming the recess 65, portions oi the flanges 32, 42 of the body members 20, 21 are carried inwardly, as at 66, to outline the recess 65 lower edges of the and the Yface plate 22 is correspondingly carried inwardly in its upper halt, as at 6?, to wall said recess 65 and engage the inset portions 660i said flanges. 'The face-plate 22 at the upper and lower sides of the forward portion 68 of the recess 65 are formed with openings 69 for the passage ot the brake-shoe lrey. The head shown in Fig.r11 will have both the hanger opening 28 and the hanger opening 65 so that the head may be used interchangeably in equipments requiring the hanger opening 28 and those requiring` the upper hanger opening 65. The head shown in Figs. 1 to 10 having been so ullv described, it is believed further de- 11 is not required, since both heads are alike in all details with the exception hereinbeore noted. l will however apply to Fig. 11 a 'ew of the reference numerals from Fig. 1 applicable thereto.

The face plate of Figs. 11 and 12 is the same as the face-plate 22 shown in Figs. 1 Aand 4, with the exception that it has the inset portion 67 and key-openings 69 incident to providing the upper hanger-opening or recess 65.

vln Figs. 13, 14, I illustrate the head of 1 equipped with an upper hanger opening 70 extending transversely through the side plates 23, 41 ot the head. In forming the opening 70, l force the metal in the plates 23, 41 in the Zone of the opening outwardly in opposie directions and curl the iianges thus Jformed to surround the opening, as indicated at 71, 72 in Fig. 14, whereby the opening becomes formed and its edges are broadened, rounded and reinforced. Since the head shown in Figs. 13 and 14 differs from the head shown in Figs. 1 to 10 inclusive only in respect to the additional hanger opening 70', it is believed that further description with respect to Figs. 13 and 14 is unnecessary. l will. however, identity some of the features of Figs. 13 and 14 with the reference numerals applicable thereto from the head shown in Figs. 1 and 2.

ln the several forms oi3 my invention shown there is no departure from the main principle of my invention, each head shown being ot 'forged metal and having the two vertical substantially equal body members 20, 21 and tace plate 22 and each head being devoid of transverse joints and constructed with the View of fully withstanding the great strains to which in modern railway equipment brake-shoe heads are subjected.

l do not limit the invention to all of the details of form and arrangement hereinbefore described, since these will vary with special requirements, as, for illustration, the socket formed in the head for the end of the compression member must have a shape to closely receive the end of the compression member made use of whether that member deiines a square in cross section or has a rounded back surface or otherwise varies in cross-section.

I have also referred to rivets 18 for securing the face-plate to the body-po-rtion of the head, and in lieu of rivets spot-welding may be used as a substitute therefor.

I prefer to secure the members 20, 21 together along their back edges by means of tlae. turned-over and ciof'ed fiange 35, but I am aware that said members may be secured together, with probably less convenience and advantage, by means other than a. foldedover flange.

lVhere in the claims I refer to a tension member nut or a nut-seat, I do not limit the claims to the presence of a nut on the tension member but only to a seat adapted to receive a tension member or truss-rod nut or such means as may be provided for securing the rod in place, as, for instance, by heading its end instead of using a nut. I may add also that I do not limit my invention to an inc-lined nut-seat, since in some brake-beams the ends of the truss rod lie parallel with the ends of the beam member and in such bea-ms the nut-seats are flat and parallel with the outer faces of the heads.
